SPECIFICATION forming part of Letters Patent No. 443,032, dated December16, 1890.

Application filed October 5, 1888. Serial No. 287,335. (No model.)

T to whom it may concern.-

Be it known that I, HENRY ABBOTT, of Newark, in the county of Essex andState of New Jersey, have'invented certain new and useful Improvementsin Inking-Pads for Type \Vriting Machines; and I do hereby declare thatthe following is a full, clear, and exact description thereof, referencebeing had to the accompanying drawings, in which--- Figure 1 is aperspective view from beneath of the parts of my inking-pad separatefrom each other. Fig. 2 is a like view of the same combined, and Fig. 3is a vertical central section of said pad and its connecting mechanismasarranged for use in a typewriting machine.

Letters of like name and kind refer to like parts in each ofthe'figures.

Myinvention relates to a type-writing machine in which the printing isdone by ink applied directly to the face of the type and is'intended foruse in printing, in a different color from that used upon the typegenerally, a character or mark for distinguishing letters that areintended for capitals; and to this end my said invention consists incombining with a type-writing machine inking mechanism whereby inkshaving different colors may be simultaneously employed for printing,substantially as and for the purpose hereinafter specified.

In the carrying of my invention into practice I employ an annular pieceof felt .A for an ink-holder and place the same upon a correspondinglyshaped metal plate B, that around its outer edge has a flange b, whichprojects upward around the edge of said felt. Over said felt there isnow placed an annular plate c,which covers the entire upper surface ofthe same and preferably extends inward beyond its inner edge. Theink-pad A and its inclosing plates B and C are now placed within arecess d, that is formedin the top plate D or housing of the machine,and the whole locked in place therein by means of a metal ring E, whichis provided with a peripheral exteriorly-threadecl flange c, and fitsinto the recess over said parts with its threaded periphery inengagement with the correspondingly-Lbreaded side of said recess. Asthus arranged, the inking-pad A is inclosed and supported from above,while a considerable portion of its lower side is exposed'and isimpinged upon by each of an annular row of type F and F as they returnto their normal positions after having been moved inward and upward tothe center for the purpose of printing their characters upon paper thatis suitably supported above.

One of the type F is provided with a character that when printed inconnection with the ordinary letters of the type operates arbitrarily toconvert the same into a capital. Such distinguishing character may beprinted around or at one side of the letter, or it may consist of anornamental background for such letter 5 but under anycircumstancesitbecomes much more effective if printed in a different color from thatused upon the balance of the type. To permit of the use of a differentcolor, the portion a of the pad A immediately over the distinguishingcharacter is removed and within a threaded opening 0 in the plate 0 isfitted a threaded metal casing c, that is shaped like a cartridge-shelland within its lower open end contains a correspondingly-shaped piece offelt 0 that is saturated with ink having the desired color. The size andlocation of the supplemental pad (3 are such as to adapt it to receivethe impingement of the special-character type F, by which means saidtype is always in condition to printits distinguishing mark in thepredetermined color. The casing c entirely separates the main andsupplemental inking -pads and enables entirely different kinds of ink tobe employed without difficulty.

For the purpose of insuring the relative horizontal positions of thepads A and c and the plates B and O a stud or pin 0 projects from theplate B down through an opening a in said pad and through anotheropening I) in said plate B. Said pin is preferably arranged immediatelyoutside of the supplemental padcasing c, as shown. The required verticalposition of said supplemental pad 0 is secured by the rotation of itsthreaded cas ing or holder 0 within the threaded opening a, by whichmeans each of said inking-pads is entirely independent and may beadjusted to its type without interference with the other.

Having thus described my invention, what I claim is 1. In a typewritingmachine, in combination with the independently movable types thereof,the inking devices consisting of an inking-pad adapted to supply ink toa portion of said types, and having an opening in which is placedanother supplemental pad adapted to supply ink to the remainder of suchtypes, substantially as and for the purpose specified.

2. I11 a type-writing machine, in combination with theindependently-movable types thereof, the inking devices consisting of anannular pad adapted to supply ink to a portion of said types, and havingan opening in which is placed an independent incased pad adapted tosupply ink to the remainder of such types, substantially as and for thepurpose shown.

In an inking device for a type-writing machine, the combination of aninking-pad adapted to supply ink to a portion of the printing-types, aplate placed over said pad, and a second pad supported from said plateand adapted to supplyink to the remainder of such types, substantiallyas and for the purpose set forth,

4. In an inking device for type-writingmachines, the combination of aninking-pad adapted to supply ink to a portion of the printing-types, thecasing for such pad, and a second pad adjustably supported by said easing and adapted to supply ink to the remainder of such types,substantially as and for the purpose specified.

5. In an inking device for type-writers, the combination of aninking-pad, the plates incasing it, and the incased supplemental padsupported by one of said plates, substantially as and for the purposeset forth.

6. In an inking device for type-writing machines, the combination of anannular inking-pad perforated at one point, the platesinclosing it uponits upper and lower sides, the supplemental pad arranged within suchperforation, and the casing for the latter pad attached to said upperplate, substantially as and for the purpose shown.

7. In an inking device for type-writingmachines, the combination of aninking-pad, the plates incasing it, the supplemental pad, and thescrew-threaded casing therefor engaging an opening in one of saidplates, substantially as and for the purpose described.

8. In an inking device for type-writing machines, the combination of aninking-pad having a section removed, a supplemental pad adapted to beplaced in the space formed by the removal of said section, and means foreffecting and preserving the registration of said supplemental pad withsaid space, substantially as and for the purpose specified.

0. In aninking device for type-writing machines, the combination of aninking-pad, the plates incasing it, the supplemental pad inserted in anopening in the former pad, and the pin for insuring the position of thelatter in such opening, substantially as and for the purpose shown.

In testimony that I claim the foregoing I have hereunto set my hand this21st day of August, 1888.

HENRY ABBOTT.
